TotalBoat White and Neutral Gelcoats

Isophthalic White and Neutral Gelcoats create a durable, shiny finish, and are available with & without wax additive.

Gelcoat with wax makes the final gelcoat layer cure to a hard sandable finish, with no wax paper or special tools needed.

Gelcoat without wax additive is ideal if you're laying up a mold for a new boat or a fiberglass part where you're laying down the gelcoat first, then applying more layers of resin and fiberglass on top. In this case, you don't want the gelcoat to cure completely.

Neutral gelcoat is better with coloring agents. White is more opaque with coloring agents.

MEKP is included as the catalyst. To thin, use styrene (sold separately).

Available in Quart and Gallon Kits, and a 5-Gallon size (resin and MEKP only) Wax additive also available for use with gelcoat without wax.

BONUS! Each Quart and Gallon size Kit order includes:

  • 1 Qt. size plastic mixing pot
  • 1 10" wooden stir stick
  • 1 pr. of large latex gloves
  • 2 plastic pipettes for transferring the MEKP catalyst to the mixing cup

The gelcoat you are buying is an Isophthalic NPG gelcoat with or without wax additive.

The gelcoat without wax is used for layups when you want the initial layer of gelcoat to remain tacky to the touch while you're laying reinforcement plies on top in order to create a strong chemical bond in the laminate. If you use unwaxed gelcoat as the finish coating, you must spray PVA (polyvinyl alcohol) over it or use wax paper or some other means to effect a proper cure.

The gelcoat with wax is used for an air dry post-applied application. The wax additive rises to the surface, making a film that creates an air barrier, allowing the final gelcoat layer to cure properly.

IMPORTANT - Do not Apply Gelcoat Directly on TotalFair:

Gelcoat should not be applied directly over TotalBoat TotalFair epoxy fairing compound or the gelcoat will not cure properly. Instead, apply TotalBoat 2-Part Epoxy Primer or TotalBoat TotalProtect Epoxy Barrier Coat Primer over TotalFair, before applying Gelcoat. Primers are sold separately.

MIXING DIRECTIONSs: NOTE: The higher the percentage of catalyst, the faster the gelcoat will dry. Air and surface temperature will also affect the drying of the gelcoat. The colder the air temperature, the higher the percentage of catalyst you should use.

TotalBoat Gelcoat requires MEKP (methyl ethyl ketone peroxide) catalyst to cure. As with all polyester resin, rate and degree of cure are a function of catalyst concentration and of temperature. Resin and work area should be between 70°F and 95°F to ensure satisfactory results.

At 77°F, TotalBoat Gelcoat requires the addition of 2% MEKP catalyst, by volume: 14-16 drops per ounce, or 2 teaspoons per pint, for a working time of 10-15 minutes. The amount of catalyst may be adjusted in small, incremental amounts, either upward or downward, to account for temperature differences (more for cooler temperatures, and less for warmer temperatures). The acceptable amount of MEKP is 1-3%. Do not use more or less catalyst than this or you may get an improper cure, with laminates exhibiting moderate to severe post cure after demolding. Once cured, the gelcoat can be dewaxed, wet sanded, and buffed.

If using a wooden mixing stick, place the stick in the resin before adding catalyst so the wood doesn't absorb the catalyst.

Directions for Wax Additive (sold separately)

Wax additive is a mixture of paraffin and styrene. When adding it to gelcoat, you must also add the MEKP catalyst. Wax additive is added to the gelcoat on the final layer of a wet layup to create a tack-free surface that sands easily before applying the finish coating. Wax additive is not needed when additional layers or gelcoat are applied on top. Add 20 drops of Wax Additive per ounce of TotalBoat Gelcoat Without Wax. Note that in temperatures below 70°F, the paraffin can solidify in the container. Place the container in the sun or in front of a lamp to liquefy. USE CAUTION - WAX ADDITIVE IS FLAMMABLE!

Wax additive is available in 1 oz. and 4 oz. bottles. Refer to the table below for how much wax additive to add to gelcoat without wax. Too much wax additive will result in fish eye and other undesirable results.

Amount of Gelcoat w/o Wax  Wax Additive Required 
1 ounce  20 drops 
1 pint (16 oz.)  1/4 ounce 
1 quart (32 oz.)  1/2 ounce to 1 ounce 
1 gallon  2 ounces to 4 ounces

Very easy to use, I would buy this again!


Used for surface blemishes and minor stress cracks


Kentucky Lake


Worked much better than I expected.


I used the White Gelcoat with wax, because the repair that I was doing had to be exposed to air. I figured I would have problems with it since the weather I had to apply it in was not ideal. To my surprise it set up and cured perfectly. No soft spots at all. I love the stuff.

The best in the game


I used afternoon inreplaced my entire floor, great product that dries faster than I thought it would. For the money these guys are the best. West Marine charges twice the amount as these guys. Jamestown distributors is he reason I was able to finish my floor at a reasonable price


Toms River NJ


Excellent product.


I was a bit overly cautious on the amt of hardener that I added. (10 drops to 1/10th quart). it took 3 hours to cure but turned out just the same...FYI


North Carolina


Terrible Instructions


JD givese conflicting instructions on mixing MEPK depending on where you look. The gel coat bottle says 2 tsp per quart. Ok, but what if I need to mix 2 ounces? The website instructions caution against exceeding 2% (what would happen if you add too much?). Then, the Gel Coat video part 2 says never add more than 30% MEPK!!! I get that cooler temps will require more MEPK, but what's the deal!!? JD provides no good resource to help the noob use the product if they have tool and shop skills but zero experience with gel coat.

Was close to 98 Bayliner off white, once if I can figure out to get it closer to that color, it works well any way you like your soup.




performed as advertised


Used this gel coat to refinish the bottom of a sliding board from a houseboat. Covered nicely and hardened fully in about a day at 65degrees.


Warren, Pa


Great Product


My transom had the outboard pushed through it.Did a complete transom rebuild.Excellent coverage to re-gelcoat the exterior transom.The hardest part is getting it smooth


McDonough, Ga


TotalBoat White Gelcoats


Used this to gelcoat back side of travel trailer with tons of spider cracks and a bit of fiberglass damage. Easy to mix. My results were average because settings on air equip were off. I finished with a foam roller. The age of the trailer dictated a perfect finish was not in order. Included wax made drying time < 24hrs as it was abt 75 sq ft. Overall happy as this was my first time using gelcoat.


NW Florida


Great product


Used this to repair some cracks and scratches. Worked great and easy to use.
